Face gaze practice Baby supine position, head in the midline position, the mother in the baby’s flat 15-20 cm distance from the sound, to attract the baby’s attention, let it see after gently move the face (left and right horizontal direction 180 degrees to move) the best continuous pursuit of two 180 degrees. Baby prone position, lift the head 45 degrees -90 degrees when the midline position, let it see after gently move (left and right horizontal direction 180 degrees to move), in the practice of the mother’s expression should be rich, with a smile, so as to attract the attention of the child. By looking at the mother’s face, in addition to strengthening the baby’s eyesight, but also to promote parent-child relations, strengthen the baby’s ability to communicate with others, and enhance the baby’s ability to imitate. Object gaze exercise With black and white card or red ball, baby supine position, head center line position, red ball in the baby flat about 20 cm distance, red ball (in situ rolling) black and white card (tapping), to attract the baby’s attention, let it see after gently move the red ball, black and white card (left and right horizontal direction of the 180-degree movement) the best continuous pursuit of the two 180-degree. Effective baby can increase the difficulty, slightly up and down 45 degrees. Baby prone position, head up 45 degrees – 90 degrees when the center line position, let it see after gently move the card (left and right horizontal direction 180 degrees to move). 0 to 2 months You can use red wool embroidery for baby to catch sight. Show your baby more black and white patterns. Patterns can be in the form of rings, bars, or curves. As long as they are in black and white, babies will gaze at them for a longer period of time. 2～4 months Your baby can look at objects at a distance and gradually follow moving objects with his/her eyes from left to right and from top to bottom. At this time, toys with sounds should be moved up, down, left and right to match the baby’s gaze. 4-8 months The space in the home should be fully utilized to stimulate the baby’s vision. For example, put brightly colored pictures on the walls and show your baby brightly colored books. You will find that he is especially attracted to brightly colored papers, clothes and toys. 8 to 12 months At this time, you should take your baby outdoors more often, and he will become more and more fond of the colorful world. Although your baby cannot recognize red, yellow, and blue at this time, you can consciously say to your baby, “This is a red flower, and that is green grass.” Distinguish between light and dark, black and white, and outlines Less than 1 month old babies, although what they see is still blurred, but they can already sense the presence or absence of light in the space, and appear to turn their heads to look at the light source of the action. At an average age of 1.5 to 2.5 months, babies will have a clear response to patterns or objects with strong contrasts between black and white and high brightness, and can sense the dark areas of light and backlight in the environment, but are not yet able to distinguish their boundaries clearly, and the objects they see are only rough outlines. Recognizing internal details and colors Babies before 6 months of age have an increasingly strong sense of the shapes and colors of objects. Mothers and fathers can detect the progress of their visual function from the baby’s preference for certain colors and brightness. Babies at this time do not know what red, black, but can be more clearly know that these colors are different, so if the child responds well to color, parents usually may wish to play more color games with him. Red, yellow, blue, green, and black and white contrasting toys, the most able to attract the baby’s attention. Pink, pink and blue, natural colors and other colors are not enough stimulation and not easy to distinguish, not suitable for the early stages of visual enlightenment. At 6 or 7 months of age, babies can see other people’s features more and more clearly, unlike before when they could only perceive vague outlines. Therefore, parents should increase the opportunities for interaction with their children and provide visual stimulation opportunities. Depth perception is gradually improving. Depth perception is the so-called three-dimensional perception. In the early stages of visual development, children’s eyes show flat images, and then gradually develop three-dimensional images such as distance, nearness, left and right, height and so on. When three-dimensional perception begins to develop varies from child to child, but on average, it is established by the age of one year. The reason why human beings are able to see is that the sensory receivers in the eyes absorb light, focus it on the visual center, and then present an image. The establishment of stereoscopic perception means that both eyes are functioning normally and are more coordinated. On the other hand, if depth perception does not develop smoothly, it may affect the child’s movement, stereoscopic sense, sense of direction, etc. The importance of this should not be underestimated. Distinguishing the similarities and differences between two similar objects At about one and a half years old, children have the ability to distinguish the similarities and differences between common and similar objects in their daily lives, and as they practice more often and improve their abilities in all aspects, they will be able to distinguish more and more subtle parts of the objects. Parents can start by using simple pictures or two dolls with slightly different designs as props, and ask the child to find out the differences between the two, so as to train the child’s ability to distinguish between the two. Visual discrimination has a profound impact on a child’s development. For example, to learn properly or to deal with trivial matters in life, they all need to be able to recognize the difference between the two. Thankfully, visual acuity is not only related to the innate structure of the child, but the ability to see faster and more accurately is crucial to practice, and this is something that parents can do together with their children.
